Kember and Pierce reconvened as Spacemen 3 and produced two more albums — 1989’s Playing with Fireand 1991’s Recurring — before splitting acrimoniously. Pierce went on to form Spiritualized, whose music was used to sell Volkswagens. Kember went on to record both as Spectrum and E.A.R. (Experimental Audio Research) — and both of which blur the lines somewhat between solo efforts and collaborations — sometimes with pioneering electronic genius Delia Derbyshire.

Spectrum released four albums in the 1990s and E.A.R. have, to date, released eleven albums but as Sonic Boom remains a one album wonder. In 2012, Spectrum was released on vinyl in 2012 by Spain’s ViNiLiSSSiMO. It was also re-released on aluminum the same year by Space Age Recordings.
